DISINTEGRATING-MACHINE.

Patented Feb. 20, 1906.

Application filed August 13, 1904:. Serial No. 220,665.

To all whom it may concern.-

Be it known that I, MILTON F. WILLIAMS, a citizen of the United States,residing at St. Louis, Missouri, have invented a certain new and usefulImprovement in Disintegrating- Machines, of which the following isa'full, elear,'and exact description, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which Figure 1 is aside elevational view, partly insection, of a shredding and pulverizing machineconstructed in accordancewith my invention. Fig. 2 is a fragmentary sectional view through aportion of the disintegratingchamber, the hopper including thebreakerplate, and the grinding-plate with the adj ustments therefor.Fig. 3 is a fragmentary end view of the machine, showing the adjustingdevices; and Fig. 4 is a modified form of hopper and connection betweenthe grindingplate and breaker-plate.

This invention relates to a machine for disintegrating or pulverizingmaterial-such, for example, as the machine shown and described in myPatent No. 726,602, dated April 28, 1903; and one of the objects of theinvention is to provide means whereby the breaker-plate and thegrinding-plate in the machine may be synchronously adjusted so thatirrespective of the adjustment of the two plates their relativepositions will not be changed.

With these and other objects in view the invention consists in theconstruction, arrangement, and combination of the several parts, allaswill be hereinafter described and afterward pointed out in the claims.

The reference -numeral 1 designates the base of the machine, which isprovided with base-flanges 2. The base carries the usual disintegratingcasing or chamber 3, which in this instance is provided with elongatedopenings or slots 4. A grinding-plate 5 is slidab y Supported within thedisintegratin chamber 3 on shoulders formed on the wal s of saidchamber, as shown in Fig. 2, said grinding-plate 5 being in the form ofa hollow segment comprising a steam-jacket carrying pipes 6, one ofwhich is an inlet-pipe and the other an outlet-pipe.

Supported at one end of the machine are bearing-support brackets 7,which consist of approximately rectangular frames, on the top edges ofwhich are the bearing-blocks 8 to receive the shaft 9 of a hollowcylindrical breaker-plate 10, similar to the one illustrated in mypatent above referred to. As hereto-- fore stated, it is the purpose ofthis invention to provide means whereby this breaker-plate and thegrinding-plate may be synchronously adjusted so that their relativepositions will be permanent. This is preferably accomplished byproviding the lower bars 11 of the brackets 7 with slots 12, throughwhich bolts or other suitable fastening devices 13 project, saidfastening devices being rigid with the base 1.

On the opposite sides of the base are lugs 14 for the reception of thethreaded adjusting devices 15, which project through said lugs andare'permitted to rotate, but are held against reciprocating movement bythe collars 16 and 17. These adjusting devices are threaded in thevertical bars of the brackets, so that the rotation of the adjustingdevices will cause the brackets to slide upon the base in a directionwhich may be governed by the direction of rotation of the adjustingdevice. In order that both brackets may be adjusted simultaneously, Ihave provided sprockets 18 on said adjusting devices, and on one of themI have provided a hand-wheel 19, so that said adjusting devices may beoperated in an an obvious manner.

Projecting through the slots 4 in the chamber-casing 3 are projectionsor lugs 20, which are rigid with the grinding plate 5. The rods 21 areconnected to these projections 20 and to the bearing-brackets 7, so thatwhenever the brackets are moved movement will be imparted to theindinglate through the medium of the re s21,-the imit of movement of thegrinding-platebein g governed by the lengths of the slots land theadjusting movement of the breaker-plate shaft being permitted by theslots 22 in the disintegrating-chamber casing. The hopper 23 at the feedend of the machine is provided with a the concentrical movement of thesteam-jacket rear wall 24, which is rigid with the hopper portion of themachine, so that From the foregoing it will be obvious that the singleadjusting means for controlling the position of the breaker-plate willefiectually cause the grinding plate to move synchronously with saidbreaker-plate, so that the relative positions of the two plates will notbi: changed at any adjusted position of either p ate.

/ In Fig. 4 are shown the roller breaker-plate and links 27, mounted onthe axles thereof, said links being1 pivotally connected .to lugsrojecting on t e under sides of curved si e ars, mounted in guideways inthe side frames of the machine. These side bars, which are indicated at28, carry cage-bars, (indicated at 29.) In this way the connectionbetween the roller breaker-plate and the grindingsurface is within thecasing instead of being outside of the casing, as shown in Figs. 1, 2,and 3. In the construction shown in Fig. 4 the roller breaker-plate maybe adjustedhorizontally, of concentric movement with respect to the axisof rotation of the pivotedrevolving hammers which cooperate with thebreaker-plate and said grindmg-plate. The pivotal con- .nection betweensaid roller breaker-plate and inding- .plate is such that while the breaer-plate moves horizontally the grinding-plate may moveconcentricallyybut the relative positions of the breakerlate andind-ing-plate will not appreciably e change Having thus described myinvention, what I claim as new, and desire to secure by LettersPatent,is v 1. In a machine of the class described, the

combination with a disinte ating-chamber, a hop er, a rotary breaker-pate and a grindvided with a rotary beater, a horizontally-ad'- ing-pate, of means for imparting synchronous movement to the rotarybreakerlate and grinding-plate for urposes of a justmen t; substantiallyas escribed.

2. In a machine of the class described projustable rotarybreaker-platef'a grindingplate concentrically ad ustable wit respectto'the axis of rotation of the beater, the

The shaft 'horizonta y-adjustab while the grinding-plate iscapable siaio' breaker-plate being adjacent to the entrance opening ofthe machine and the grindingp ate being immediately below saidbreakerplate, and means for imparting synchronous movement to thebreaker-plate and grinding-plate; substantiall as described.

- 3. In a machine of the class described provided with rotary beaters, ahorizontally-adjustable rotary breaker plate, a grindingplateconcentrically adjustable with respect to the axis of rotation of thebeaters, and a connecting means between the two whereby the movement ofone will impart movement to the other; substantially as described.
